How to write a villain

Some of the next titles are going to be 1 2 3 and every now and then something different so let's start

Eclipse

Background
Eclipse, born as Lucien Noir, grew up in a life shrouded in darkness-both figuratively and literally. Raised in a family of thieves and mercenaries, Lucien was trained in deception, combat, and survival skills from a young age. He learned quickly that trust was a liability, and his experiences fostered an incredibly self-sufficient yet isolated personality. Growing up without genuine relationships, he turned to his powers to gain control over his life, eventually becoming one of the most elusive criminals, known as Eclipse.

Appearance
Eclipse's appearance matches his dark abilities. He has pale skin, shoulder-length black hair, and piercing, almost silver-grey eyes that seem to absorb light. He wears a sleek, all-black tactical outfit with dark armor plates and a long cloak that billows around him, seamlessly blending him into the shadows. His suit has specialized technology that enhances his stealth abilities and protects him from potential counterattacks.

Personality
Cold, calculated, and highly strategic, Eclipse rarely lets his guard down, always assessing situations and people for potential advantages. He is an introvert, preferring to work alone rather than in groups. Eclipse has little patience for inefficiency or carelessness and despises loud, flashy displays of power. He admires subtlety, precision, and control, and he takes immense pride in his ability to disappear without a trace. Despite his cold exterior, Eclipse harbors a quiet resentment toward society, feeling that it never offered him a fair chance. This bitterness drives his desire to use his powers to challenge and disrupt the social order.

Abilities
Eclipse possesses the power to manipulate shadows, allowing him to blend into darkness, move silently, and even teleport short distances using shadow portals. Here's a breakdown of his main abilities:

Shadow Blending: Eclipse can merge with any shadow, rendering him nearly invisible in dark environments. This ability works in low-light conditions, which he often creates using gadgets, allowing him to disappear from sight almost instantly.

Teleportation through Shadows: Eclipse can create small portals through shadows, allowing him to move quickly from one dark spot to another within a limited range. This makes him highly elusive, as he can vanish from one location and reappear in another within seconds.

Shadow Tendrils: In combat, Eclipse can manipulate shadows to create tendrils or dark constructs, allowing him to restrain, trap, or trip up his enemies. These shadow constructs are intangible and ephemeral, but they can still disorient or temporarily incapacitate opponents.

Shadow Armor: When threatened, Eclipse can encase himself in a layer of shadow that acts as a form of armor. While it doesn't offer full protection, it absorbs and dampens incoming attacks, especially energy-based ones.

Umbral Vision: His eyes have adjusted to low-light vision, allowing him to see in total darkness. This gives him an immense advantage in dark environments, making him even more dangerous at night.

Weaknesses
Eclipse's powers are significantly weakened in brightly lit or sunlit areas, where shadows are minimal. He's particularly vulnerable during daylight or in open, well-lit spaces, where he has fewer opportunities to use his abilities. Additionally, any sudden or intense light sources, like flashbangs or floodlights, can disrupt his focus and abilities. Physically, while he is agile, Eclipse lacks the superhuman strength or durability of some other villains and relies on stealth rather than direct confrontation.

Motivations
Eclipse's ultimate goal is to dismantle the hierarchies and social structures he believes have oppressed people like him. He sees himself as a liberator, showing society the chaos that lurks in the shadows. His disdain for "heroes" stems from his belief that they maintain an illusion of safety and order that he considers hypocritical.

Reputation
As a villain, Eclipse has gained a fearsome reputation as the "Shadow Reaper," known for his unmatched stealth and lethal efficiency. Law enforcement finds him nearly impossible to track, and the rare survivors of his attacks speak of a figure that appeared from the darkness, leaving only shadows in his wake. Many underestimate him initially, seeing only his lack of brute strength, but those who underestimate Eclipse rarely get a second chance.
